It's probably non of my business and I'm BU but on the way back from town I was queuing at the traffic lights. This family with I think a 7 year old boy were walking up the road. The boy was shouting and swearing at the cars, sticking his middle finger up, hitting the cars and at one point got his willie out. I would be sooo embarrassed if my DS ever acted in such a way and he would definitely be told off have some form of punishment
(I'm in no way a perfect parent but even I know that that sort of behaviour is not acceptable)
But all his family did was laugh and encourage him 
No real point to this except that I was more than a little miffed that his parents did fuck all to correct his behaviour and even more miffed that they encouraged it.
